I am trying to add the result of a variable f to the end of a list list_name. However, when I try to do this I get the following error:
list_name.append[f]
TypeError: 'builtin_function_or_method' object is not subscriptable
What am I doing wrong?
list_name.append(f)
append is a method (function) so you should call it with simple parentheses.
And of course, a function is not subscriptable, so you get an error...
(An object is subscriptable when it has a __getitem__ method.)

(starting code) My code is showing (TypeError: 'NoneType' object is not iterable) error even the variable I am using is contains some value. This is the code I am talking about
The problem is in how you are appending values to your list users_cards.
You have written users_cards = users_cards.append(random.choice(cards)).
The append function automatically updates the object so the code should read: users_cards.append(random.choice(cards)) (no need for the users_cards = bit)
Your user_cards is None. You need an iterable there (list, tuple etc) because you've used sum function on that. Make sure user_cards is initialized.
hope you are all in safe. I just wanted to get (20^5)-(1^5)/5(20-1)
myNum = ((20**5)-(1**5))/5(20-1)
print(myNum)
I took the TypeError: 'int' object is not callable
Then I changed it like;
print(((20**5)-(1**5))/5(20-1))
But I'm still getting same error. I checked the solutions but didn't understand what am I have to do.
Fix: ((20**5)-(1**5))/5/(20-1)
Error is that you can't omit multiply sign here: 5(20-1).
Interpreter considers you're trying to call function like f(...), but 5 is not a function, that's why you see error:
TypeError: 'int' object is not callable
^^^ ^^^^^^^^
5 (20-1)
I have a fucntion like:
def image_process(ind):
return rotate(img[ind])
I am calling this function with Pool.imap to construct a generator
something like:
gen= pool.imap(image_process,[1,2,3,4,5,6],chunksize=100)
However, this generator seems to be empty. I can't run a forloop over it.
As soon as the interpreter reaches the following line:
for k,im in enumerate(gen) it throws an error: TypeError 'int' object has no attribute 'getitem'
I have the following two lines of code:
print(test)
print(test.type())
There is something being printed out by the code, namely the value of test. However, when I check the type of test through test.type(), i get the error TypeError: 'NoneType' object is not callable. How is this possible?
test.type is None.
Use type(test) instead.
So I try to pass this through Python:
print("Strength:",stats[0])
print("Defense:",stats[1])
print("Agility:",stats[2])
...and I get this in return:
TypeError: 'function' object is not subscriptable
What does this mean and how do I fix it?
It means that stats is a function instead of a sequence. Perhaps you forgot the parens on an earlier function call.
